Randomized Controlled TrialComparison of the Ambu Aura-i with the Air-Q Intubating Laryngeal Airway as A Conduit for Fiberoptic-guided Tracheal Intubation in Children with Ear Deformity.
Objective To compare the Ambu Aura-i with the Air-Q intubating laryngeal airway for fiberoptic-guided tracheal intubation in ear deformity children. Methods Totally 120 children who were scheduled for elective auricular reconstruction surgery requiring general anaesthesia with tracheal intubation were enrolled in this prospective study. They were randomized to receive either the Ambu Aura-i (Aura-i group) or Air-Q (Air-Q group). ⋯ Hemodynamic changes were not significantly different between two group. The incidence rate of sore throat two hours after operation was 6.5% (n=4) in the Air-Q group and 5% (n=3) in the Aura-i group. Conclusion Both Ambu Aura-i and Air-Q intubating laryngeal airway are effective conduits for beroptic-guided tracheal intubation, with advantages including simple operation, high success rate, and fewer complications, especially the Ambu Aura-i.

Randomized Controlled TrialInfluence of Anesthetic Brochure on Patient's Information Gain, Preoperative Anxiety, Trust, and Satisfaction.
Objective To assess the impacts of anesthetic brochure on anesthetic information gain, preoperative anxiety, trust to anesthesiologists, and satisfaction to the preanesthesia visit for patients undergoing general anesthesia. Methods Totally 134 patients scheduled for elective thyroid surgery under general anesthesia in Peking Union Medical College Hospital were assigned to two groups using the random number table method, among whom 68 patients received brochure before preoperative visit (brochure group) and 66 patients did not (control group). Questionnaires with items for evaluating patient's information gain, preoperative anxiety and trust were completed after preanesthetic visit. ⋯ Results Compared with the control group, patients in the brochure group had significantly higher information gain scores (7.2±1.8 vs. 5.2±2.1, P<0.001) and satisfaction scores (25.0±3.4 vs. 22.7±3.1, P<0.001). There was no significant difference in anxiety scores and trust scores between these two groups. Conclusion Preoperative anesthetic brochure-assisted education can improve information gain and satisfaction among patients undergoing general anesthesia; however, it can not remarkably alter patient's preoperative anxiety and trust.

Effects of Two Intranasal Dexmedetomidine Doses as Premedication on Sevoflurane EC50 for Successful Laryngeal Mask Airway Placement in Children.
Objective To observe the effects of two different intranasal dexmedetomidine doses as premedication on the EC50 of sevoflurane for successful laryngeal mask airway placement in children. Methods Children aged 3-6 years, of American Society of Anesthesiologists physical status 1, and scheduled for plastic surgery were enrolled in this study. Children were assigned to receive either spray administration of intranasal dexmedetomidine 1 μg/kg (group D1, n=21) or 2 μg/kg (group D2, n=20) approximately 30 minutes before anesthesia. ⋯ Mask acceptance was 76.2% in group D1 and 90.0% in group D2. The EC50 of sevoflurane for laryngeal mask airway insertion was 1.09% (95% CI=0.89%-1.28%) in group D2, which was lower than 1.59% (95% CI=1.41%-1.78%) in group D1 (P<0.05). Conclusion Compared with the dose of 1 μg/kg, spray administration of intranasal dexmedetomidine 2 μg/kg as premedication can reduce the sevoflurane EC50 for successful laryngeal mask airway placement in children.
